V To all whom it'fmafl/ concern: c y Be itknownthat l, Vieron E. fassun- LETN, a citizen of the United States, and resident of New York, in the county of New York and State'oi New York, have invented certain new and useful vImprovements in vFuel-Control Valves for Carbureters, of

which the Vfollowing is a' specification. y

This invention relatesfto carbureters and has more especial reference to an improved fuel control valve for carbureters.

The invention has for its dominant object to provide a fuel control valve so constructed as to permit the ilow of fuel therethrough into the carbureter and to `increase or decrease or vinstantly ndiscontinue suoli liow according to the movement oi the valve.

Another and equally important object of the invention is to provide adjustal'aleV air intake means whereby vtheproper admixture of air will be obtained to permit the forming of a rich or lean explosive charge.

The foregoing together with additional advantageous details and arrangement of parts of the preferred embodiment of my invention will be clear from the specific description hereinafter contained, when read Vin connection with the accompanying drawin gs, forming parts hereof, wherein said embodinient of the invention is illustrated for the purpose of facilitating a ull understanding oi the present improvements.

In the drawings:

Figure 1 is a vertical transverse section througha fragment of a carbureter with my improved i'uel control valve applied thereto;

Fig. 2 is a similar View taken at substantially right-angles to Fig. 1; and

Fig. 8' is a detail in perspective oi' the 4o improved control valve stem.

Similar characters of reference are employed in all of the above described views to indicate corresponding parts.

Referring to the drawing in detail7 1' designates generally a portion oi' a casing forming the intake passage of a carbureter and having formed therein diametrically opposed horizontally alining openings in which are received bearings 2, said casing being provided with an outwardly curved or bellied portion 1 at one side thereof for a purpose presently described.

Engaged inthe bearings 2 is a valve stem, the seine being termed at one eatremty `Specification of Letters Batent. Patented Apr `.12 1921 7 o Application filled April 9, 1917.- Serial No. 150,778. i

with a substantially `iirusto-conical portion 4 providing the usual. plugtype of valve. rlhe valve stem has provided therein longitudinally for a portion oii its length a bore15, the inner endopening laterally through said stem to provide an air inlet port` 6, lwhile said bore near its outer end is yprovided with a lat'er'al'portion opening through the plug y.

valve el, the air inlet port being` designed Vfato permitthe admission of air into the bore 5 in said valve stem. y

A; casing element 7 is removably Viitted uponthe plug valve t-ofthe valve stem 3vr and is provided with an externally threadedy neck S adapted toreceive thereon the usual :tuel` supply conduit or pipe 9.' To properly holdthe element 7 with relationto the plug valve et a coiled spring lOis arranged about the vouter portion oi' thelatter and has its jbearings upon the head ci set screw 11 and the element 7, thes'et screw being turned into engagement with the threaded extremity of the bore 5 in the valve stem 3.

A butterfly valve 12 is mounted upon the i valve stem 3 within the casing 1, the valve being formed with a boss 18 which receives a screw 16, the latter being threaded in a suitable opening formed in the boss 13. rihis boss has provided therein outwardly divergent air ducts 15 which merge into each other and open through the butteriy valve 12 for direct communication with the air intake port 6 in the valve stein 3, the opening for the screw 16 merging into the ducts 15 so that on adjustment of the said screw inwardly the ducts 15 can be closed and to regulate the iiow of air through the ducts 15 the screw is turned in said opening.

A discharge way 17 Vis formed in the buttertly valve 12 and extends at substantially right angles to the bore 5 in the valve stem 1, the inner extremity of said way being in direct communication with the inner end of the bore 5. At the outer extremity of the way 17 a flared portion 17 4is provided.

An operating arm 18 is secured to the extremity of the valve stem 8 opposite the plug valve portion 4 and has connection with a suitable lever arranged in proximity to the operator of the engine.

A screw threaded opening is formedy in the casing 1 and has adjustably engaged therein a set screw 19, thus when it is desired to clean the discharge way 17 in the butterfly valveY 12when the latter is in one position the set screw 19 is removed, thereby giving free access to the way 17 for the in'- `troduotion of a wire into the same.

The butterliy valve 12 is made fast upon the valve stem 3 through the medium of a set screw 14 which is passed transverselyV through said stem and butterfly valve.

,In operation, to admit fuel to the carbu' reter casing l the butteriy valve 12 is turned with the valve stem 3 until thelateral portion of thebore 5 opening through the plug A valvel communicates with the port inV the .casing 7 and at; this time a small amount of fuel will bev permitted to flow from the'conduit 9 through said casing 1 and valve stem Q 3V intoy the ldischargewvay 17 inthe butterfly valve' 12 and from there the fuel :will'be discharged in vthe form .of Va spray into the. Vcarbureter. It is `evident that the supply of fuel maybe readily lincreased Vor decreased i `Vby rotating the valve stem Bon operating thearm 18 So that `thelaterally. extending portion of the bore 5 opening through the 25 plugvvalve 4 will increase in 'size with its registration with the `port in the casing 7.

" The flow of fuel may be readily vbroughtto a maximum by moving thevalve stem 3 a "predetermined cdistancethatlis to say,V to

full open position. Y

The admixture of air with the ,explosive charge canbe varied by Vadjusting the screw `stem journaledf, transversely thereinV and having an external plug valve portion, said stem being formed for a major portion ot its length with a bore having lateral por- ".tions opening through saidV stem and the plug valve, a fuel Supply means 4fitted on, the

`*plug* valve, means active upon said fuel sup-V ply means to effect a,-iluidi tight joint be- Vtweenthesame and the-plug valve@J butteriy valve fitted upon the valvestemandvmovable therewith, said `butterifly fvalve '.Abeing Vformed `with a clisoharge'way communicating with the bore in thevalvestem and disposed at lright angles to said bore, an enlargement formed on the butterfly valve and :having outwardly divergentiairi ducts oom- Vmunicating.withsaid bore, andoJ screw adl justably fitted within the enlargementand adapted to intersect the ducts.
